example 1
[0136]In this example, the OCB-mode liquid crystal display described with reference to FIGS. 1 to 7 was manufactured by the following method. It is noted that in this example, the optical compensation film 40 was formed not on the outer surface of the back substrate 10, but only on the outer surface of the front substrate 20.
[0137]First, a structure including the undercoat layer 101 to the pixel electrodes 130 was formed on a 0.5-mm-thick glass substrate 100. On this structure, an SiO2 layer and an acrylic resin layer were sequentially formed as the planarizing layer (not shown). Also, the common electrode 230 was formed on a 0.5-mm-thick glass substrate 200.
[0138]In this example, the pixel electrodes 130 had almost rectangular shapes, their pitch in the X-direction was 82 μm, and their pitch in the Y-direction was 246 μm. In each pixel electrode 130, four recesses RD and one protrusion PD were provided to the edge ER.
[0139]The length of the edge ER1 was 7 μm, the length of the edge...
example 2
[0151]In this example, the OCB-mode liquid crystal display described with reference to FIGS. 10 to 13 was manufactured by the following method. That is, the structures shown in FIGS. 10 to 13 were employed in the pixel electrodes 130, and the alignment direction AD was parallel with the X-direction. Except for them, the liquid crystal display was manufactured by the same method as that described in Example 1.
[0152]In this example, the pixel electrodes 130 had almost rectangular shapes, and their pitches in the X-direction and Y-direction were the same as Example 1. In each pixel electrode 130, five protrusions PD were provided to the edge ER and four recesses RD were provided to the edge EL.
[0153]In the protrusion PD shown in FIG. 11, the length of the edge EP1 was 7 μm, the length of the edge EP2 was 20 μm, the length of the edge EP3a was 7 μm, and the length of the edge EP3b was 10 μm. The edge EP1 was parallel with the X-direction, the angle that each of the edges EP2 and EP3b ma...
example 3
[0159]In this example, the OCB-mode liquid crystal display described with reference to FIGS. 14 and 15 was manufactured by the following method. That is, the structures shown in FIGS. 14 and 15 were employed in the pixel electrodes 130, and the alignment direction AD was rotated 180° about the axis that is parallel with the Z-direction. Except for them, the liquid crystal display was manufactured by the same method as that described in Example 1.
[0160]In this example, the pixel electrodes 130 had almost rectangular shapes, and their pitches in the X-direction and Y-direction were the same as Example 1. In each pixel electrode 130, three protrusions PU were provided to the edge ER and three recesses RD were provided to the edge EL.
[0161]In each recess RD, the length of the edge ER1 was 10 μm, the length of the edge ER2 was 5 μm, and the length of the edge ER3 was 12 μm. The angle that the edge ER1 makes with the X-direction was 45°, and the edges ER2 and ER3 were parallel with the X-...
